9V Guitar Power Supply 9 Isolated DC Output for 9V/12V/18V Effect Pedal and 1 USB Output for Mobile Devices (Lotkey LPB-03)…

Great Pocket Size Power supply. I feed a pignose T-100 and several 9v effect pedals and works perfect without any noise. I even run an 18v pedal using a doubler voltage cable. I play amplified harmonica searching the Chicago Blues tone with that hardware and this power supply is perfect size for my travel case ....and battery last hours of playing....I have not discovered yet how long would last...I just know that I play until mi lips and toungue bleed like the end of the World is comming 😊. The only but, would be that the charge of the battery is not fast....but is an advantage for me to be able to charge it with USB.... adaptaers of other brands may be faster..., but adapter needs more space in a travel case or you could forget it, otherwise, faster charges ussualy last less than a slow charge. This power source is a 10 of 10.

I specifically wrote this review because another reviewer stated that this power supply did not work with Boss pedals. I have several Boss pedals and thought that was probably false and decided to give this power supply a try. You can see from the images that I have it powering three Boss pedals and a Wampler Tumnus Deluxe, there is a 4th Boss pedal on the board but that is my tuner and it was off when the picture was taken, it also works perfect with this power supply. I have only been using this power supply for about a week, and it has worked perfectly. I have it on my small pedal board and none of these pedals draw much power, the Boss RV-6 Reverb pedal is the highest power draw on that pedal board and is rated at 95ma. I also noted that with this setup on this board there is NO noise from the power supply.It took several hours to charge when I received it and I have used it for several hours of practice and it is still going strong on its 1st charge.I love the flexibility of just reaching down and switching on the power supply without needing to plug it in. I plan to purchase four more of these and use them on my medium and large pedal boards. It would be nice if they made a larger version that could power more pedals and pedals that draw more than 300ma (there is one 300ma power port on this power supply).

On a whim, I decided to build an "afford a board". My thought experiment was to build the CHEAPEST, yet MOST FUNCTIONAL pedal board I could.I already had the tubescreamer and crybaby wah. I purchased everything other pedal on this board on Amazon Black Friday deals.I cut the wood myself because I had it laying around. This whole pedalboard only cost me $140.The CENTRAL HEART of this pedalboard is the Power Supply. It's AMAZING. I don't need to plug the pedalboard into the wall, which makes it super mobile and convenient. An added bonus is not introducing any electrical noise from a bad power socket.On a full charge, the battery lasts 10 hours! I've taken it to 3-4 performances in one week where I left it on for 3 hours at a time, with no charging in between.Lastly, it has a USB type A port. So this means you can charge your Cell phone! I elected to purchase a $10 USB reading light with a gooseneck. This provides a light so you can see your pedal board on stage!My Black Friday price was $34.39 for the power supply. That's a STEAL.These USB Battery power supplies are great. I have the perfect pedal board to take to jams and bar gigs. This whole pedalboard is cheaper then the price of one "boutique" guitar pedal. It's super practical, has a very useable sound, and is easily replaceable price wise if damaged or stolen.

Edit: This battery can't power an Ammoon EQ7 7-band EQ. When plugged in, the pedal works but produces a loud electrical whine.The good:- Powers 7 pedals as advertised. See my board photo for proof (yes the Wally looper is on and working).- No noise for me. Previously I was using a daisy chain power supply, and noise would bleed from my chorus and looper into into my distortion pedals. This PSU fixed it.- Smaller and slimmer than expected.The ok:- can't use the USB-A output at the same time as the pedal outputs: the PSU gets overloaded and turns off. I was hoping I could power an 8th pedal via USB but seems it's not possible.The bad:- only one 300ma port is very limiting. Most analogue pedals (overdrives, distortions, analogue modulation) will be under 100ma. However, many digital pedals (delays, reverbs, pitchshift, loopers) will be over 100ma. Check the power requirements in your pedal owner manuals very carefully before buying.- Other reviews state the outputs aren't really isolated. I *currently* get no noise, but it's not guaranteed. It's you're crazy about getting zero noise, then be prepared to test and return.

This caused a high frequency squeal when I tried using the 12v output to run my tc helicon harmony g-xt. That's a deal breaker for me, and it was returned.

I hate wall warts,and daisy chains because of ac hum,and I especially hate using 9v batteries which can leak& corrode and destroy expensive pedals.It may not have 12v capability like the ridiculously expensive cios power supplys,but it seems to hold a charge for a long time,is light and small in size. And most of a quiet with no hum.I haven't bothered to check resistance with my fluke meter to see if its truely isolated.I really don't care.all I own is quality 9v effects pedals, and this suits my needs.plus you can charge your cell phone with it when the power goes out.Could have come in handy when power was off in Boston for over a week this past winter.I got this unit in april 2022...so far its working great.

Got it for my first pedal board. Pretty compact, holds a good charge, and great for portability. Velcro it to the board, and take it with you!

This unit..Lotkey LPB-02, when fully charged, powered 7 analog guitar pedals for 8 hours over 3 sessions (I timed with stopwatch) before finally showing signs that it was running low…a loss of power, etc…though everything still worked at 8hours and 7 minutes. Solid, quiet,…just bought 2 more.

It made my guit pedals noisey....Had to buy a better one.

La batería dura suficiente para terminar un evento grande, de una sola carga completa toqué dos dias seguidos en presentaciones de 4 horas y media cada dia, y aun asi continue usandola en la semana de manera informal sin llevar la cuenta de las horas de uso pero fácilmente me dio otras 5 horas.Los cables que trae podrian ser en el L (angulo) pero bueno, la calificación es para la pila en sí

Logré conseguirlo antes de su subida de precio y la verdad el producto se siente de calidad , vale cada peso! No he tenido la oportunidad de usarlo en una jornada de 3+ hrs de uso cómo en una tocada pero en el tiempo que lo he usado en casa (2hrs de uso continuo) no me ha fallado en lo absoluto

Esta fuente cumple con su objetivo y cabe mencionar que es muy pequeña y lo más importante, no mete ruido a los pedales, lo pude adaptar sin problema a mi pedalera hasta el momento alimento 4 pedales y no he tenido problema con la alimentación, los cables que trae se ven un poco "corrientes" pero si han aguantado y la fuente si es bonita aunque no luzca por la posición en la que la puse.

Me ha funcionado muy bien, eso si tuve que devolver una porque hacia ruido y a un amigo le fallaron, pero yo viajo con dos y no he tenido problema
